HAZWOPER Decontamination Procedures & PPE Usage 5

Question 1

What is the purpose of tape used at glove-to-sleeve and boot-to-suit interfaces during Level A or B PPE donning?

Accepted Answer

To prevent splash contamination from entering through gaps between components

Answer

Taping interfaces between gloves and sleeves and boots and suit legs prevents liquid contamination from seeping through gaps, maintaining the integrity of the chemical-protective barrier.

Question 2

During decontamination, rinsate collected from washing contaminated PPE must be:

Accepted Answer

Managed as hazardous waste unless testing confirms it is non-hazardous

Answer

Decontamination rinsate is considered potentially hazardous and must be collected, characterized, and managed as hazardous waste unless analytical testing confirms it is non-hazardous.

Question 3

A HAZWOPER instructor is teaching the concept of 'degradation' in PPE. Which scenario BEST illustrates degradation?

Accepted Answer

A chemical causes a butyl rubber glove to swell and soften

Answer

Degradation refers to physical changes to PPE material—such as swelling, softening, hardening, or discoloration—caused by chemical contact, reducing the material's protective properties.

Question 4

Which OSHA standard requires employers at hazardous waste cleanup sites to establish a decontamination procedure before any employee enters areas where potential for exposure exists?

Accepted Answer

29 CFR 1910.120(k)

Answer

29 CFR 1910.120(k) specifically requires employers to develop and implement decontamination procedures before employees enter areas where potential contamination exists at hazardous waste operations and emergency response sites.

Question 5

When should air monitoring be conducted relative to decontamination operations at a hazardous waste site?

Accepted Answer

Continuously, including monitoring the decon corridor and breathing zone of decon workers

Answer

Air monitoring should be continuous and include the decontamination corridor because decon workers handling contaminated PPE and equipment may be exposed to off-gassing or splashed contaminants.
